' To all 207mm it may concern:

Be it known that I, JEROME B. Sncon, a citizen or" the United States,residing at Derby, in the county of New Haven and State of Connecticut,have invented certain new and usetnl Improvements in Type ritingMachines, of which the following is aspecification. I

My invention relates to the paper feeding and controlling devices intype-writing machines, particularly those adapted for use in connectionwith those machines in which the types strike upwardly and rearwardlytoward the front side of the platen, or, front strike machines, socalled.

The object of my invention is to provide devices of the character setforth for the more convenient and rapid handling and adjustment of thepaper or record sheets in the use of type-writing machines for writingbills and records. It is customary in many establishments to renderbills of account to their customers at weekly or monthly intervals, butto make the entry of the items upon those bills at the time the goodsare delivered, and,at the time of making such entry make one or morememorandum copies of the particular item of that date one of which mayaccompany the shipment and the others be retained for use in otherdepartments. In many cases the record sheets are retained, as theycontain the entries of successive bills. These record sheets may be ofconsiderable length and are not removed from the machine between themaking of entries thereon; only the shorter memorandum bill and recordsare removed. In this removal the paper feed rolls are released as usual,which would ordinarily free the record sheet so that in such removal ofthe bill the record sheet'would also 'be movable and by being moved theregistry of its written lines to the writing point would be lost,necessitatinga read justment. My devices are intended to obviate thisdisadvantage by providing-means that will securely hold this recordsheet in registry during such time as the usual feed rolls are releasedand means for providing a registry point for the edges of the new billwhen it is inserted over the record sheet, so that when the feed rollsare engaged it Specification of Letters Patent.

Will be in proper registry with the record sheet beneath it.

The device for carrying out my invention is associated with and isoperated by the usual feed roll release lever in an en- "tirelyautomatic manner and is so arranged My invention consists of thefeatures of novel construction, arrangement of parts and combination ofdevices having for their objects the above and other ends; describedandillustrated in the accompanying drawings and specification andaccompanying claims.

The platen 6 is mounted on the paper carriage7., .which has the usual long tudinal, incitement-"for providing forletter spacing at, eachipi-inting operation under the control of niainspring and escapement mechanisms whichare not shown.

The platen 6 is revolved for line space feeding by means of the linespace lever 8, (see Fig. 2) in a step by step manner, by means of a pawloperating on the ratchet wheel 9 and for varying distances at the willof the operator by means of thethunib wheel 10. Cooperating with theplaten 6 to feed the paper, the front feed rolls 11 and the rear v feedrolls 12 "are provided, see Figs. 3, 4, 5,

7,. and 9. The front feed rolls 11 are held against the platen '6' bythe spiral springs 13, Figs. 2 and 7, one end of which are attached tothecarriage frame and the other to the ends of the shaft14 on which thefeed rolls revolve. The shaft 14 held in alinement with the platen 6 bythe slots 15 in the carwhich riage fram The front feed rolls arereleased or thrown'out of engagement with the. platen by the feed rollrelease lever 16 v is fixed to the shaft 14. The heel of this lever 16terminates in a cam portion comprising two curved seats with anintermediate detent. The axes of the curves of .these seats are atdifferent radial distances from the axis of the shaft 14. ln'Figs. 3,

4, andf these curved seats are designated as 17 and 18 and theintermediate detent as 19. A duplicate of this heel portion of the lever16 is mounted on the opposite end of the shaft 14 and operatessimultaneously therewith. These cam plates have a floating axis in theaxis of their connecting shaft 14. The curved seats are held againstscribed are the rollers 20 by the tension of'the springs 13, drawing theshaft 14 upward in the slots 15 which are in line with the axis of therollers 20 which have bearings on studs 21 fixed in the'carriage frame7. The axis of the normal seat '17 is nearest the axis of the shaft 14and when this seat is in engagement'with the roller 20, the feed roll 11is in engagement with the platen as shown in Fig. 3. \Vhen the lever 16is oscillated forward as shown in Fig. 4 the detent 19 rides over theperiphery of the roller 20. and the seat 18 embraces said roller and theaxis of this seat, being at a greater distance from the axis of theshaft 14, this shaft and the rolls 11 are forced radially away from andout of enga ement with the platen 6. The rear paper springs 22 the rearunder side of the paper table 23. The paper table 23 is supported bygthe' sheet metal brackets 24 on the rod 25 which extends intermediatethe ends of the carriage 7, see Fig. 3. The feed roll 12 is disengagedfrom as the front roll 11. This is accomplished as follows: The stud pin26 which is can ried by the heel of the paper feed roll release lver '16engages the forward end of' the lever 27 When the release lever isoperated to operate lever 27 on its pivotal support 28 which is fixed inthe carriage frame, the rear end of lever 27 is depressed andbears uponthe roller 29 which roller is mounted on the forward end of the lever30.

This lever/3O extends rearwardly and has a bearing support on the rod25. Thislever is at the right hand end of the carriage and its rear endis bent to the left and extends parallel with the rod 25 to a pointintermediate .the ends of the carriage where' it again extends forwardlyas the lever 31 which also has-a. bearing support on the -rod'25 andbears upon thc'upperside of the shaft 32 upon which the sections whichmake up the rear feed-roll 12 are mounted. As the forward end of lever31 is thereby depressed through the instrumentality of the roll 29 onlever 30, the feed-roll 12 is disengaged from the platen 6 at the sametime as the feed-roll 11. The in the position shown in Fig. 4 by thedetent 19 as is the case with the feed-roll 1-1. The relative positionsof the-parts just dofully illustrated in the two views, Figs. 3 and L,in which they are the platen at the same time i eedroll 12 is suspendedon the which have their attachment on feed-roll 12 is held shown in boththe engaged and releascdpositions.

Attached to the under rear side of the paper-table 23 are the stiffeningplates 33 whichextend down between the paper table and thesupportingbrackets 24, there being one of these plates at each end ofthe paper table. From these plates extend arms -H beyond the ends of thepaper table and "end to end at the rear of 1,1ao,19o w then are bent atright angles so that they extend upwardly and forwardly to serve as abearing support for the rock-shaft 35 which extends across the papertable from the platen 6. Rigidly attached to the rocleshaft 35 are theradial arms 36 which extend forwardly with their ends terminating in aline intermediate the writing point and the top of the platen. Attachedto 36 is the record sheet clamp plate 37. The rock-shaft 35 is operatedby the lever 38. This lever is in the form of a split grip comprisingthe members 39 and 40 of which 40 is a spring. They are held together bythe screws 41., One end of the member 39 is formed into an eye portionwhich encircles the rock-shaft 35, which at this point is halfsquaredasshown in Fig. 5 to present two right angled faces 42 and 43 with anintermediate detent 4A. As shown in dotted outline in Fig. 6, the end ofthe spring member 40 is narrowed and normally lies in spring contactwith the flattened surface 43 and maintaining a yielding but operativeconnection for the lever 38 with the rockshaft As shown in'Fig. 6, oneedge of this lever lies below the roll 29 on the lever 30 and is held inconstant contact therewith by the leaf spring 45 attached to the papertable 23, which also serves to maintain the arms 36 and the record sheetclamp 37 in a normally elevated position, as illustrated in Figs. 3 and5. When these parts are in this normal position, the paper feed-rolls 11and 12 are closed or in engagement with the platen 3. When the feed-rollrelease lever 16 isdrawn forward to release the feed-rolls and free thepaper or sundry sheets which may be interposed between the feed-rollsand the platen, the roll 29 is thereby depressed hereinbefore describedcarrying with it the forward end of the lever 38, which operates todepress the forward ends of the arms 36 and the record sheet clampingbar 37 in engagement with platen 6 at a point intermediate the printingpoint and the top of the platen, engaging any sheets which may have beenso placed in the machine as to pass underneath the same and holding themin register with the writing line, while any sheets which do not passunder this bar may be removed from the machine without disturbing thesesheets and others inserted intheir stead.

If it is desired to tempmarily dispense 'with the use of the recordsheet clamp, the

bar andthe arms 36 are forced upwardly, and rearwardly to the positionshown in the dotted outline in Fig. 5. t

1 forces the spring member 43 awa e axis of this shaft and the flattenediii engages the spring member, thus aining the r cord sheet clampingdcthe forward ends of the arms W hen this is done, the machine.

25' 33 is cranked on the shaft 35, the

vice in an inoperative position as shown.

These parts may be readily placed in this po- I In Fig. 9 is shown aportion of the left hand end of the paper table 23 with a portion of therecord sheet clamp 37 hearing graduations M5 which correspond with thoseon the regular paper and carriage scales l7 and 48, Fig. 2. These arefor convenience in setting the record sheets with reference to verticalrulings.

In Fig. 8 is shown a modification of the clamping means in which springfingers 37 replace the arms 36 and the bar 37. Their operation andfunction are the same as in the preferred construction alreadydescribed. In this figure a portion only of the paper table 23,rock-shaft 35 and platen 6 are shown.

Referring to Figs. 2 and 5: 51 is my improved line-indicating andpapergaging paper guides. These paper-guides are sheet metal plates,curved at their upper portion to conform with the radius of the platen6. At an intermediate point at 55 they are bent to form a shoulder orabutment from which point they are flat or straight to their support onthe carriage scale" bar 48, on which they are slidably mounted by thehousing 54. These paper guides may be moved along on the scale bar 48 toengage the edges of sheets of paper of different widths by the fingerloops 56 which are formed up from an extension of the metal of thehousing bent forwardly and back as shown in Fig. 1. These paper guidesare prevented from passing the printing point -to the possible injury ofthe types striking on metal, by the stops 57 which are also formed outof the body of the sheet metal housing by striking up the forwardlyprojecting tongue which forms these stops as shown in Figs. 1 and 5. Inthe movements of the carriage right and left, the stops 57 will engagethe type-bar guide plate 58 at its edges, arresting the progress of thepaper guides beyond that point if the operator should inadvertently seteither of these guides within the printing field intermediate the pointsdetermined by the right and left margin guides usually found on alltypewriting machines. I These paper guides are provided with lineindicating perforations 51 which perforations are semicircular in form,the straight lower side of which indicates the bottom of a written lineas shown in Fig. 2. The shoulder at 55 serves a very useful purpose inthe placing of paper in Vhen the paper feed rolls are released, a sheetof paper or in fact several sheets with accompanying carbon sheets maybe passed between the feed-rolls and the platen and their forward edgesbrought up to and in abutment with this shoulder,

which enables the operator to square the sheets with the laten and to'secure a definite starting point for the sheets. When the'feed rollshave been closed and the paper fed forward, the leading edges are forcedpast this shoulder and between the-paperwriting line, is fed-.above theclamping bar 37! 4 50, in'the same figure, represents a rec- ,ord sheetand its accompanying carbon sheet, which, as it leaves the writing line,passes beneath the clamplng bar 37 and is in a position to be engagedthereby when the feed rolls are opened by the operation of the lever 16as shown in Fig. i. When the feed rolls are thus opened, the closing orengagement of the clamping bar takes place, the two separate paperclamping means engaging andreengaging invariably in inverse-ordeiag Thefeed rolls operate to feed, thepaper during rotation of the platen andhold the same during the writing operation.- The clamping bar is for thepurpose of holding a. selected number of the sheets in engagement withthe platen when the same is stationary with their 'written'lines inregistry with the writing line. In inserting the record and carbonsheets, the clamping bar will be raised as shown in the dotted outlineinFig. 5, and the. feed rolls will be released as shown inFig. 4. Thesheets will then be passed in over the paper table as usual and thelocation of the first writing line positioned by the line gages 53, seeFig. 2. when the clamping bar will be lowered to the position shown inFig. 4 engaging the sheets in that position. Additional sheets or abill'is then inserted with their or its advance edges directed to pass overthe clamping bar 37, and similarly positioned, when the feed 'rolls areclosed as in Fig. 8, clamping the same and the record sheets to theplaten in condition for simultaneous line-space feed, the clamping bar37 now being disengaged. \Vhen this first operation is completed thefeed rolls are opened, releasing all the sheets from line-space feed andfeed roll engagement with the platen while the record sheets are engagedby the clamping bar and heldin fixed relation thereto. The bill or othersheets may now be removed and others inserted in their places with theiradvance edges ordinarily in abutment with the edge of the bar 37. Thefeed rolls are then closed "as before and the platen line-spaced. tobring a new line on the record sheets to the writing line and the.desired space on the new bill to the same point, when the work is.

proceeded with as before. Thus it will be seen that I provide a devicewhich automatically engages the sheets thatthe opera-tor against saidplaten.
